摘要
Controlled superdense coding with multi-particle GHZ state and multi-particles GHZ-class state via local measurement are explicitly exploited in this article. The amount of information transmitted from the senders to the receiver is controlled by the supervisor via his local measurement. It is shown that the amount of information is determined by the supervisor's measurement in the former case of GHZ state, and by the supervisor's measurement and the coefficients of the original GHZ-class state in the latter case.
